IKE Debug on R81 and above

AndréTinoco — Thu, 07 Oct 2021 12:26:53 GMT

Hello CheckMates,

I came across this today and decided to share as I did not find any information anywhere else.

Even though skI4326 includes R81 and R81.10, ike.elg and ikev2.xml are not created by the debug commands as in the previous versions.

From version R81, the files that are created/populated are:

$FWDIR/log/legacy_ike.elg
$FWDIR/log/legacy_ikev2.xml

The debug methods remain the same.

Best regards,

André Tinoco

I have given your findings as a feedback to sk34467, sk63560 and skI4326 !

skI4326 has been changed to include:

...

Starting from R81.10 version, the 'vpn debug' commands also trigger the debug output for the new daemons iked and cccd, if they are enabled (with the "vpn iked enable" and "vpn cccd enable" commands):

File Description	VPND Log File	IKED Log File	CCCD Log File
Main debug output file	$FWDIR/log/vpnd.elg	$FWDIR/log/iked.elg	$FWDIR/log/cccd.elg
IKEv1 output	$FWDIR/log/legacy_ike.elg	$FWDIR/log/ike.elg	N / A
IKEv2 output	$FWDIR/log/legacy_ikev2.xmll	$FWDIR/log/ikev2.xmll	N / A

Still no changes in sk34467 and sk63560

Hmm. R81.10 introduces the new cccd daemon that also comes with a ccc alias to it.
I wonder if my awarded ccc script might cause an issue or if I can safely advice to install it as usual in /usr/bin/ccc, because after installation and re-login to expert mode ccc execution runs my script instead of cccd.

Hello, I am trying to debug my VPN connection, but files are not being created. How can I fix this?

Hello AkosBakos,

this script executes the built-in commands, but exactly with them i have a problem: the log files are not being created.

Hi,

Yes, it executes the same commands. Whit this, you can avoid of the copy paste errors 🙂

Have you tried the same commands on a different gateway?

What is exact debug you ran? I always follow below steps and worked fine even in R82 lab.

Andy

vpn debug trunc

vpn debug ikeon

-generate some traffic

vpn debug ikeoff

Look for vpnd* and ike* files in $FWDIR/log dir
